Mackie Stingray is Sylia Stingray's younger brother and her only family. He serves as the Knight Sabers backup and mechanic along with Sylia's friend, Dr. Raven. Mackie is a whiz kid with computers and technology. He has to constantly make repairs to Priss's bike because of her driving and the situations she gets into. He can pilot an armored suit himself and drives a large truck that delivers the Knight Sabers and their bikes to a situation. Mackie's character is also extremely perverted, trying to catch his sister (as well as the other Knight Sabers) in the nude as much as he can.
